"It's just life. I'm sure you've all witnessed a break-up. It's life. Work, my health, his job, the children -- life is overwhelming for everybody," Yolanda shared. "It's a lot of work to keep it all together."

Recently, Yolanda and her 65-year-old husband sold their 12,000-square-foot beachfront mansion in Malibu, and the two celebrated the sale with a sweet photo of themselves kissing on their breathtaking back patio in front of a stunning sunset.

According to Yolanda, they sold the home so she could focus on her struggle with Lyme disease. However, her illness has come under fire from some of her RHOBH castmates this season, and Yolanda opened up about how she deals with such accusations and rumors.

"I just let it roll off my back because I have nothing to prove to anybody except to myself," the reality star explained. "To be honest with you, it doesn't faze me - I've heard it for so many years now that it goes in one ear and out the other."

According to Yolanda, she now has "laser focus" and she's directing all of her efforts and attention toward getting better so she can "teach the world a lesson about Lyme disease."
